I don’t remember the name but the cover was blue.
I think there was a house on the cover.
There was a dog and a boy that were friends.
One of the character’s name was John.

Some kids went on an adventure.
It was one of the ones with the books and the monsters.
It took place in a school.
It had a murder and a detective.
We all have books that we love and we may not remember the names or the author.
Every.
Single.
Day.
I have a patron come up to me with a phrase similar to the ones above.
Every.
Single.
Day.
They don’t remember any pertinent information but they think from these random details I will just know what book it is. I have shelves and shelves of books in my department and I’m expected to remember the covers, characters, and have read all of the books to help you find this particular one. (Insert banging head against the wall).
Over time I’ve gotten much better at parsing these things out. Asking for more details. Helping the reader discern what they are actually looking for but most of my time lends to a very Sherlock Holmes kind of experience.

I really don’t know why people aren’t more amazed at our being able to figure out what they wanted! I mean we take all of this nonsense and inconsequential details and VOILA! Here’s your book! The answer to your question! The destination of your journey! We have delivered it to you! …. And the patron is never impressed. But alas, we do it. We search and scour and glean and sift until finally your desired book is hand delivered to you. From every Librarian out there- you’re welcome world
